v6.4.0

Release 6.4.0 — 2026-11-09

Summary

ycc 6.4.0 adds the mcp-parity skill for planning and syncing a Linear project with one issue per API/app capability, maps the Haiku model tier to @task for OMP, and pins the OMP unpin built-in so the OMP built-in command check passes.

Added

• mcp-parity skill (/ycc:mcp-parity) researches a repo's API or app surface and creates or syncs a Linear project, milestones, and prioritized issues for one-to-one MCP parity. Re-runs apply only the delta (added, changed, removed, revived) via a manifest Document, with deterministic diffing in capability_diff.py, OpenAPI 3.x inventories via openapi_inventory.py, and surface hints from detect-api-surface.sh (#540, closes #539).
• OMP model policy: haiku maps to @task, and code-finder now runs on haiku.

Changed

• code-finder agent model: sonnet → haiku.

Removed

• None this release.

Fixed

• OMP built-in command pin: unpin is now in the reserved-name set in scripts/generate_omp_commands.py, so scripts/omp_builtin_commands.py passes against the live omp (18.18.1).

v6.3.1

Release 6.3.1 — 2026-11-05

Summary

ycc 6.3.1 fixes duplicate ycc skills, agents, commands and MCP servers in opencode. install and sync --target opencode now add the @yandy-r/ycc-opencode npm plugin to opencode.json instead of copying the bundle into ~/.config/opencode, and retire the old copies that ycc can prove it wrote.

Added

• install --target opencode writes one plugins entry. --mode local (default) points it at this checkout's packages/opencode/ycc-opencode; --mode repo pins @yandy-r/ycc-opencode@<version> from npm. --package @yandy-r/ycc-opencode does the same.

Changed

• @yandy-r/ycc-opencode is now the primary opencode package (no longer experimental or opt-in). Settings, rules (AGENTS.md) and the opt-in plugin catalog stay on the installer.
• The generated .opencode-plugin/opencode.json no longer lists the ./ycc-sensitive-guard plugin or an mcp block; the package ships both.
• Release notes no longer mark the npm package "not yet published".

Removed

• opencode file copies (skills, agents, commands, shared helpers, the guard directory) and the opencode MCP merge.
• --mcps, --agents, --commands, list-mcps, --skills-home and its duplicate-skills prompt. --skills and --with-deps now apply to the agents target only.

Fixed

da77850 fix(opencode)!: install the @yandy-r/ycc-opencode npm plugin instead of copying the bundle (YAN-1973) (#536)

• A ycc-written, bare or @latest @yandy-r/ycc-opencode entry is replaced in place, keeping its options. A pinned version you set yourself, or another checkout's directory, is kept unless you pass --force.
• The legacy cleanup runs only after the package is confirmed loadable: package.json in local mode, the npm release in repo mode, and opencode 2.0.30 or later when opencode is on PATH. It removes only byte-identical copies, owned mcp.servers entries and the owned guard item. Edited and foreign entries are kept, and a symlinked opencode.json is refused.

v6.3.0

Release 6.3.0 — 2026-11-05

Summary

ycc 6.3.0 makes install.sh native-only. install and sync now install Claude, Codex and Cursor through their plugin CLIs (ycc-mcp@ycc and ycc-hooks@ycc included), and they clean up files left by older installs, but only files ycc can prove it wrote. The legacy file-copy and config-merge routes and the migrate subcommand are gone.

Added

977fbb6 feat(install)!: install natively only; drop legacy install routes (YAN-1962) (#534)

• Claude: --intent mcp installs ycc-mcp@ycc and --intent hooks installs ycc-hooks@ycc, at project scope by default and user scope with --global. This fixes refusing to replace directory with symlink: ~/.claude/hooks.
• Codex: base installs ycc@ycc and ycc-mcp@ycc with codex plugin add, and --intent mcp installs ycc-mcp@ycc.
• Cursor: install registers the GitHub marketplace with agent plugin marketplace add and lists which packages to select in /plugins.
• OMP: old omp plugin link and marketplace installs are cleaned up during install.

Changed

• The legacy cleanup (formerly migrate --apply) runs as part of install, sync and remove --intent base. It removes only files identical to what ycc wrote, links ycc owns, and config entries ycc recorded. Edited copies and your own files are kept and reported. If the cleanup fails, it prints a warning and the install continues.

Removed

977fbb6 feat(install)!: install natively only; drop legacy install routes (YAN-1962) (#534)

• The migrate subcommand (--apply, --marketplace-source) and the deprecation hints.
• Claude: the ~/.claude/hooks symlink, the settings hooks merge, the MCP merge into ~/.claude.json / .mcp.json, and standalone skill, agent and command copies.
• Codex: the local-ycc-plugins catalog, plugin symlinks, cache copies for Codex builds older than 0.160, the [mcp_servers] merge and standalone skill copies.
• Cursor: every file copy (skills, agents, commands, rules bundle, the hooks carrier, the MCP merge).
• --skills, --agents, --commands, --mcps, --with-deps, --skills-home and --hooks <events> for claude, codex, cursor and omp. They still apply to opencode and agents.

Fixed

• remove --target cursor --intent <content> no longer drops the whole ycc marketplace; only --intent base does.

v6.2.1

Release 6.2.1 — 2026-11-04

Summary

ycc 6.2.1 removes the linear-personal MCP server from ycc-mcp on every runtime; linear is now the only Linear server. It also fixes saved external_directory approvals in the opencode npm package and a CRLF .gitignore check in branch prep, and registers the deferred Pi target in the package model.

v6.2.0

Release 6.2.0 — 2026-11-04

Summary

ycc 6.2.0 adds the artifact store: planning, implementation, review and report skills can keep their artifacts as Linear documents and issues (with a local .ycc/artifacts/ cache) instead of docs/plans and docs/prps files, and ycc:init records the choice in a committed pointer. Linear is now the default store for repositories without a store configuration; existing local plans and reviews keep working. install.sh gains --dry-run on every target and step, and project scope for the settings step and Claude hooks.

v6.1.0

Release 6.1.0 — 2026-10-23

Summary

ycc 6.1.0 adds native support for OMP (oh-my-pi), with omp 18.12.2 or later. The ycc, ycc-mcp and ycc-rules OMP packages are listed in the root .omp-plugin/marketplace.json. install.sh --target omp installs, updates, removes and migrates them at user or project scope. The release also adds item selection to install.sh (--skills, --agents, --commands, --plugins, --mods, --hooks and --with-deps), and fixes for the opencode restricted-agent permissions. A new live CI workflow runs the OMP acceptance harnesses against pinned omp releases on Linux and macOS.

v6.0.0

Release 6.0.0 — 2026-10-17

Summary

ycc 6.0.0 ships native packages in every runtime marketplace. Claude now lists ycc-mcp, ycc-hooks, and ycc-all alongside ycc; Codex lists ycc and ycc-mcp in a renamed ycc catalog; and Cursor gains a root marketplace with ycc, ycc-mcp, ycc-hooks, and ycc-rules. install.sh file copy remains the fallback, and install.sh migrate moves an existing install to the native packages.

Validation

• ./scripts/sync.sh — OK
• ./scripts/validate.sh — OK
• python3 -m json.tool .claude-plugin/marketplace.json — OK
• python3 -m json.tool ycc/.claude-plugin/plugin.json — OK

Upgrade Notes

Breaking

• Codex MCP moved to ycc-mcp. The Codex ycc plugin no longer ships .mcp.json
  or declares mcpServers. Install ycc-mcp@ycc to keep the MCP servers.
• Codex marketplace renamed. .agents/plugins/marketplace.json is now the ycc
  catalog with local sources at ./.codex-plugin/ycc and ./.codex-plugin/ycc-mcp.
  It replaces the local-ycc-plugins catalog and its ./plugins/ycc source, so
  ycc@local-ycc-plugins installs must move to ycc@ycc and ycc-mcp@ycc.
• Cursor native layout. Native Cursor packages live under packages/cursor/
  and are listed in a root .cursor-plugin/marketplace.json.
• Codex skill paths. Helper paths in the Codex ycc bundle now resolve relative
  to each SKILL.md instead of ~/.codex/plugins/ycc/.

Upgrade steps

Preview each migration first, then apply it:

./install.sh migrate --target claude
./install.sh migrate --target claude --apply
./install.sh migrate --target codex
./install.sh migrate --target codex --apply
./install.sh migrate --target cursor
./install.sh migrate --target cursor --apply

• Claude: ycc-hooks@ycc needs Claude Code 2.1.300 or later. Migration prunes
  installer hooks only after ycc-hooks@ycc is enabled, and installer MCP entries
  only after ycc-mcp@ycc is enabled; ycc-all@ycc alone proves neither.
• Codex: migration registers the ycc catalog and installs ycc and ycc-mcp
  before it retires the legacy entry. `~/.codex/a...

v5.3.0

Release 5.3.0 — 2026-10-15

Summary

ycc moves skill-managed worktrees to per-runtime, repo-local roots (.claude/, .codex/, .cursor/, .opencode/worktrees/), makes AGENTS.md the canonical rules file emitted by ycc:init, and retires the ycc/commands/ wrapper layer in favor of native skill invocations. Validators gain a practices ratchet plus .claude/rules frontmatter and root-import budget checks, maintainer and destructive workflows are marked user-invocation-only, and a large maintenance pass splits oversized skills into lazy references.

• ./scripts/validate.sh — OK
• python3 -m json.tool .claude-plugin/marketplace.json — OK
• python3 -m json.tool ycc/.claude-plugin/plugin.json — OK

Upgrade Notes

No breaking changes to skill or agent names. Plugin-based installs need no action; standalone and repo-local installs have the follow-ups below.

• Wrapper commands retired (#232). ycc/commands/ no longer exists; public skills are the native slash invocations (/ycc:<skill> on Claude). Invocation is unchanged for plugin installs. Standalone Claude installs that previously wrote wrappers to ~/.claude/commands are cleaned up on the next skills install: re-run ./install.sh sync --target claude --intent skills (alias: --intent commands). Only wrappers recorded in ~/.config/ycc/installed-units.json are removed; your own files in ~/.claude/commands are never touched. opencode keeps one generated command per public skill (~/.config/opencode/commands/); re-sync to refresh it: ./install.sh sync --target opencode --intent skills,commands. Update any scripts or docs that reference ycc/commands/*.md paths.
• Worktree roots moved (#277). Skill-managed worktrees are now created inside the repository under a per-runtime root: .claude/worktrees/ (Claude), .opencode/worktrees/ (opencode), .codex/worktrees/ (Codex), .cursor/worktrees/ (Cursor); the cross-tool agents bundle auto-detects its runtime and falls back to .agents/worktrees/. The former roots (~/.claude-worktrees/, <repo>/.config/opencode/worktrees/) are retired: existing worktrees there are not migrated or removed and keep working, but new runs use the new roots. Add the root for each runtime you use to .gitignore (e.g. .claude/worktrees/, .opencode/worktrees/) before committing, and clean up old worktrees with git worktree list / git worktree remove <path>. Set YCC_WORKTREE_ROOT to override the root explicitly. The Claude worktree-create hook now defaults to <repo-root>/.claude/worktrees; native harness worktrees (opencode tools, Codex, Cursor) keep their own placement.
• AGENTS.md is the canonical rules file (#263, #266, #269). ycc:init and ycc:release-model now emit and target AGENTS.md, with CLAUDE.md as a thin importer (@AGENTS.md). Repos with legacy layouts keep working; run /ycc:init --migrate-rules --dry-run (then /ycc:init --migrate-rules) to move an existing long CLAUDE.md into AGENTS.md. Shipped user-global rules were slimmed to a tool-neutral ruleset and Cursor rules were pruned and scoped, so re-sync rules after upgrading: ./install.sh sync --target <claude|cursor|codex|opencode> --intent rules. Repositories that adopt the new validators need paths: frontmatter on every .claude/rules/*.md file and a single standalone @AGENTS.md import in CLAUDE.md (#276).
• Maintainer/destructive skills are manual-only (#234). backport, blueprint, bundle-author, bundle-release, clean, compatibility-audit, git-cleanup, hooks-workflow and releaser now carry disable-model-invocation: true (Codex: allow_implicit_invocation: false; opencode: autoinvoke: 'false'). They remain user-invocable but models will no longer select them automatically. Re-sync skills to pick this up.
• GitHub MCP default changed (1e52cf6, cc197a6). The default GitHub MCP entry moves from the deprecated npm package / PAT remote to the native github-mcp-server stdio binary (browser OAuth). ycc sync --intent mcp migrates recognized legacy entries; custom GitHub setups are preserved unless --force. Install the github-mcp-server binary and complete the OAuth prompt on first use. An inherited GITHUB_PERSONAL_ACCESS_TOKEN or GITHUB_API_TOKEN overrides browser OAuth; unset it to use OAuth. The repository's project-local .mcp.json was removed (not part of the shipped bundle).
• Skill/agent maintenance. Many oversized skills were split into lazy references and trigger descriptions were shortened/sharpened; the git-cleanup agent is now read-only and agent frontmatter/tool scopes were cleaned. No renames or removals.
